Nice, can you tell a huge difference before/after??
It did make a pretty good difference. heres a rundown of what I did for the sound deadening:
what I did was get a couple rolls or Raamat and used it in the most needed places (i.e. I wend around and tapped on the sheetmetal to find places that resonated more than others, like big flat areas, etc) the 2 rolls was just enough to cover all the places I felt were really necessary, for me I used a tennis ball to help smooth it and push it on to get good adhesion (I also cleaned all the surfaces beforehand with denatured alcohol, to promote proper adhesion). then I had a bunch or Second Skin Spetrum (the paint on stuff. it actually is pretty good stuff), I think I had around 4 or 5 gallons of it, and after the raamat was on really well, I went through and put a few coats on everything, letting it dry for at least 12-14 hours before the next coat. Then after the last coat was dry, I used some spray glue and glued some ensolite closed cell foam and glued it over the major areas (i.e. floor, inside doors, etc) and did double layers with the extra I had in spots like under the sub (its a down firing single 10") and behind the door speakers. after that, I got some expanding foam from Home Depot, its called 'Great Stuff' its expanding insulation to fill the gaps between window frames, and used it to fill in and add ridgitity and insulation inside the gaps between the rear pillar sheet metal (this was after running my rear speaker wiring too).
